In the past three decades, grass-covered countries, grassland fertilization area and the amount of fertilizer increased sharply, and its yield-increasing effect is significant, but our work in this area is still only in the trial stage, especially forage Feishi fertilizer, in this Before the test, the domestic has not yet reported.
